Electrochemical gas sensor Wikipedia

Sensors are usually designed so that the gas supply is limited by diffusion and thus the output from the sensor is linearly proportional to the gas concentration. This linear output is one of the advantages of electrochemical sensors over other sensor technologies, ( infrared), whose output must be linearized before they can be used.

How Do Electrochemical Sensors Work? Analytical ...

Mar 17, 2021· To put things simply, this sensor type works by means of gas diffusion. Gas finds its way into the outlet of the membrane on top of the sensor housing. Once the gas reaches the working electrode, an electrochemical reaction occurs. This reaction is either an oxidation or a reduction, depending on the type of gas.

How Electrochemical Gas Sensors and Detectors Work

An electrochemical gas sensor is available for just about any target gas, and across a wide range of sensitivities, such as a highly accurate electrochemical CO sensor. Although they are designed to be as specific as possible, most electrochemical sensors will respond in some manner to gases other than the target gas.
